4 Installation 4 Pump Body Dirt and Scale Plug Pump and Pipes Use New Pipe for Best Results. Clean Flow! Figure 1 No Dirt or Scale in Suction Pipe Before you install your pump NOTICE: Well must not be more than 20 depth to water. 1. Long runs and many fittings increase friction and reduce flow. Locate pump as close to well as possible: use as few elbows and fittings as possible. 2. Be sure well is clear of sand. Sand will plug the pump and void the warranty. 3. Protect pump and all piping from freezing. Freezing will split pipe, damage pump and void the warranty. Check locally for frost protection requirements (usually pipe must be 12 below frost line and pump must be insulated). 4. Be sure all pipes and foot valve are clean and in good shape. 5. No air pockets in suction pipe. 6. No leaks in suction pipe. Use PTFE pipe thread sealant tape to seal pipe joints. 7. Unions installed near pump and well will aid in servicing. Leave room to use wrenches. 8 Risk of explosion. Pump body may explode if used as a booster pump. DO NOT use in a booster appli cation. NOTICE: Use the installation method which matches your well type. 9. Install a check valve in the pump suction port. Be sure that the flow arrow points toward the pump. Failure to install a check valve on the inlet side of the pump may allow the pump body to drain between pump cycles, causing dry running, seal or internal failure, and voiding the warranty. No Sags No air leaks In Suction pipe. Use PTFE pipe thread sealant tape or pipe joint compound approved for use on PVC. If air flows water won t Sags Allow Air Pockets If Air Pockets Form, Water Won t Flow. Keep Pipe Straight and Angled up to Pump. Figure 2 Foot Valve Must Work Freely Figure 3 No Air Pockets in Suction Pipe Use PTFE tape. Figure 4 Suction Pipe Must Not Leak

5 Installation 5 Suction pipe 20' (6 m) max. Foot Valve Priming plug Priming tee 10-20' (3-6 m) Standing water level (pump off) Drawdown water level (pump on) At least 5 feet (1.5 m) Figure 5 Cased/Dug Well Installation Check valve Steel drive pipe Drive coupling Driven point Figure 6 Driven Point Installation Gate Valve To Service Priming Plug To Service Check Valve Gate Valve Cased Well Installation 1. Inspect foot valve to be sure it works freely. Inspect strainer to be sure it is clean. 2. Connect foot valve and strainer to the first length of suction pipe and lower pipe into well. Add sections of pipe as needed, using PTFE tape on male threads. Be sure that all suction pipe is leakproof or pump will lose prime and fail to pump. Install foot valve 10 to 20 feet below the lowest level to which water will drop while pump is operating (pumping water level). Your well driller can furnish this in formation. 3. To prevent sand and sediment from entering the pumping system, the foot valve/strainer should be at least 5 feet above the bottom of the well. 4. When the proper depth is reached, install a sanitary well seal over the pipe and in the well casing. Tighten the bolts to seal the casing. 5. When using a foot valve, a priming tee and plug as shown in Figure 5 are recommended. Dug Well Installation Same as cased well installation. Driven Point Installation 1. Connect the suction pipe to the drive point as illustrated in Figure 6. Keep horizontal pipe run as short as possible. Use PTFE pipe thread sealant tape on male pipe threads. Multiple well points may be necessary to provide sufficient water to pump. 2. Install a check valve in horizontal pipe. Flow arrow on check valve must point toward pump. Horizontal Piping From Well To Pump 1. Never install a suction pipe that is smaller than the suction port of the pump. 2. To aid priming on well point installations, install a line check valve as shown in Figure 6. Be sure check valve flow arrow points toward pump. Discharge Pipe Sizes 1. If increasing discharge pipe size, install reducer in pump discharge port. Do not increase pipe size by stages. 2. When the pump is set away from the points of water use, the discharge pipe size should be increased to reduce pressure losses caused by friction. Up to 100 run: Same size as pump discharge port. 100 to 300 run: Increase one pipe size. 300 to 600 run: Increase two pipe sizes. Sprinkling Application This pump is de signed to deliver plenty of water at full sprinkler pres sure. It can pump from a pond, cistern or well points. Pump discharge can be divided to supply two (2) or more sprinkler systems. A suggested multiple dis charge to service is shown in Figure 7. Do not use in a pressure tank or booster pump application. Pump Installation Make sure that all pipe joints in the suction pipe are air tight as well as water tight. If the suction pipe can suck air, the pump will not be able to pull water from the well. Figure 7 Multiple Discharge

6 Installation 6 Figure 8 Bolt Pump Down Figure 9 Independently Support All Piping Attached to Pump 1 Bolt pump to solid, level foundation. 2. Support all piping connected to the pump. 3. Wrap 1-1/2 to two layers of PTFE tape clockwise (as you face end of pipe) on all male threads being attached to pump. 4. Tighten joints hand tight plus 1-1/2 turns. Do not overtighten. NOTICE : Install pump as close to well head as poss ible. Long piping runs and many fittings create friction and reduce flow. NOTICE: For long horizontal pipe runs, install a priming tee between check valve and well head as shown in Figure 6. For driven point installations, install a check valve as shown in Figure 6. Be sure check valve flow arrow points toward pump. Use schedule 80 or iron pipe. See Well Pipe Installation for more information. Wiring Hazardous voltage. Follow these rules to avoid potential harm: Ground motor before connecting to electrical power supply. Failure to ground motor can cause severe or fatal electrical shock hazard. Do not ground to a gas supply line. To avoid dangerous or fatal electrical shock, turn OFF power to motor before working on electrical connections. Supply voltage must be within ±10% of nameplate voltage. Incorrect voltage can cause fire or damage motor and voids warranty. If in doubt consult a licensed electrician. Use wire size specified in Wiring Chart. If possible, connect pump to a separate branch circuit with no other appliances on it. Wire motor as shown (Figure 12B). If motor nameplate diagram does not match either Figure 12A or 12B, follow nameplate diagram. No air leaks In Suction pipe.

8 Operation 8 Figure 13 Remove Priming Plugs Figure 14 Fill Pump Before Starting 3 Figure 15 Do Not Run Pump with Discharge Shut-off. Priming The Pump NOTICE: The term priming refers to the process of pumping all the air out of the system, filling the pump and suction piping with water, and beginning to move water through the pump and out into the system. A selfpriming pump generally will repeat this process without attention once the pump and system are full of water. If the water drains out of the pump (back into the well, for example), then the whole priming process must be repeated before operating the pump again. To make sure that the pump will retain its prime (that is, that the pump and its piping will stay full of water), BE SURE to install a check valve in the pump inlet port with the flow arrow pointing towards the pump. The check valve will prevent water from siphoning out of the pump body and back down into the well, which will keep the pump full and allow it to restart on its own. DO NOT remove the recirculation valve cover (there are spring-loaded parts inside the recirculation valve see Figure 16) when priming or draining the pump. The drain is a hex-head pipe plug underneath the pump body. To drain the pump, remove the hex plug (Ref. No. 17, Repair Parts diagram). Do not disturb the recirculation valve (Ref. No. 19). If the pump or the suction pipe have been drained for any reason, BE SURE to reprime the pump before starting it. NOTICE: NEVER run the pump dry. Running the pump with out water in it will damage the seals, can melt the impellers and diffusers, and voids the warranty. To prevent damage, fill the pump with water before starting. 1. Remove priming plug (Figure 13). 2. Make sure suction and discharge valves and any hoses on discharge side of pump are open. 3. Fill pump and suction pipe with water. 4. Replace priming plug, using PTFE tape on thread; tighten plug. NOTICE: If a priming tee and plug have been provided for a long horizontal run, be sure to fill suction pipe through this tee and replace plug. (Don t forget to PTFE tape the plug.) 5. Start pump: water should be produced in 5 minutes or less, the time depending on depth to water (not more than 20 ) and length of horizontal run (10 of horizontal suction pipe = 1 of vertical lift due to friction losses in the pipe). If no water is produced within 5 minutes, stop pump, release all pressure, remove priming plug, refill and try again. Hazardous pressure and risk of ex plo sion and scalding. If pump is run con ti nu ously at no flow (that is, with discharge shut off or without priming), water may boil in pump and piping system. Under steam pressure, pipes may rupture, blow off of fittings or blow out of pump ports and scald anyone near. To prevent explosion, do the following: A. Be sure discharge (valve, pistol grip hose nozzle, etc.) is open whenever pump is running. B. If pump fails to produce water when attempting to prime, release all pressure, drain pump and refill with cold water after every two attempts. C. When priming, monitor pump and piping tempera ture. If pump or piping begin to feel warm to the touch, shut off pump and allow system to cool off. Release all pressure in system and refill pump and piping with cold water.

Maintenance If motor is replaced, replace the shaft seal and O-Rings. Keep a seal and O-Rings on hand for future use. Be sure to prime pump before starting. NOTICE: The mechanical shaft seal in the pump is water lubricated and self-adjusting. NOTICE: Drain pump (see Figure 16) when disconnecting from service or when it might freeze. You can fill the pump with RV anti-freeze (propylene glycol) to prevent it from freezing. DO NOT remove the Recirculation Valve to drain the pump (Figure 16). Remove the hex head plug on the bottom of the Pump Suction Body to drain the pump. Pump Disassembly See Repair Parts for Ref. No. references. NOTICE: Do not disturb the recirculation valve (see Figure 16). It is NOT a drain plug! 1. Shut off power to the pump before working on it. 2. Close all suction and discharge valves to isolate the pump before proceeding further. 3. Remove the hex head drain plug (Ref. No. 17) from the suction body and drain the pump. 4. Disconnect the suction line. 5. Remove four capscrews (Ref. No. 18) from the pump (see Figure 17). 6. Pull the pump suction body forward (see Figure 18). Remove the sleeve (Ref. No. 9) by pulling it straight forward. Be careful not to damage the O-rings on the bracket and suction body. 7. Remove the motor canopy, hold the motor shaft with a 7/16 open end wrench, and remove the nut and two washers (Ref. Nos. 14, 13, 12) from the end of the shaft. See Figure Slide the impellers and diffusers (Ref. Nos. 11, 10) off of the shaft (Figure 19). 9. Slide the spacer (Ref. No. 7) off of the shaft, then pull the rotating half of the seal (Ref. No. 6) forward on the shaft and remove it. 10. Block up the motor (so that the shaft will not take the weight of the motor when you loosen the capscrews holding the motor to the bracket), remove four capscrews (Ref. No. 2), and slide the motor and shaft back out of the bracket (see Figure 20). NOTICE: To avoid springing the shaft, be sure that the shaft does not take the weight of the motor as you remove it.

Turn the bracket motor side up on the bench and use a screwdriver to carefully tap the stationary seal half out of the bracket (see Figure 21). 5. Clean the seal seat cavity in the bracket. Seal Installation 1. Turn the bracket pump side up on the bench. You will need to block it up to do this (See Figure 22). 2. Clean the seal cavity in the bracket. 3. Wet the outer edge of the rubber cup on the ceramic seat with liquid soap. Be sparing! 4. Put a clean cardboard washer on the seal face. With thumb pressure, press the ceramic seal half firmly and squarely into the seal cavity. The polished face of the ceramic seat is up. If the seal will not seat correctly, remove it, placing the seal face up on the bench. Reclean the cavity. The seal should now seat correctly. 5. If the seal does not seat correctly after recleaning the cavity, place a clean cardboard washer over the polished seal face and carefully press it into place using a piece of standard 3/4 pipe as a press. NOTICE: Be sure you do not scratch the seal face. 6. Dispose of the cardboard washer and recheck the seal face to be sure it is free of dirt, foreign particles, scratches and grease. 7. Inspect the shaft to be sure it is free of nicks and scratches. Pump Reassembly 1. Bolt the bracket down to the foundation (see Figure 23). 2. Slide the motor shaft through the seal and bolt up the motor (see Figure 23). Make sure that the slinger is on the shaft between the bracket and the motor flange. Make sure that you don t chip the seal face with the shaft shoulders and that the shaft does not take the weight of the motor at any time. 2. CAREFULLY slide the rotating seal half onto the shaft, seal face first. Make sure that you don t chip the seal face on the shaft shoulders. 3. Follow the seal half with the spacer (Ref. No. 7). Slide the washer up against the seal. 4. Slide a diffuser onto the shaft (open face out) until it seats on the bracket (see Figure 24). Follow the diffuser with an impeller on a fourstage pump or with the stainless steel spacer if a three-stage pump. Engage the molded impeller key in the slot in the shaft. Don t force it! Be sure that the impeller eye, with metal ring, faces out (forward - see Figure 25). 5. Repeat step 4 with the remaining impellers and diffusers. 6. Reinstall the toothed washer, the flat washer, and the impeller nut (in that order Ref. Nos. 12,13,14) onto the motor shaft (see Figure 26). Hold the shaft and tighten the impeller nut to 10 ft.-lbs. torque. 7. Check the sleeve O-Rings; if they show any damage or wear, replace them. Reinstall the sleeve O-Rings (Ref. No. 8) on the bracket and the suction body.
